Memorial Day weekend is a good time to relax reading a suspenseful, mystery-thriller spy book. Even better if the book’s hero lives on Roosevelt Island, the author is a Roosevelt Island resident and you can get a free download of the book through Sunday.

After downloading Dark Sky , have a relaxing read on one of the

Manhattan Park Lawn hammocks.
